For example...
* Firefox 11 Nightly: 142, 419, 433, 447
* Firefox 8: 160, 897, 121, 793
* Chrome dev: 110, 87, 69, 111
* Opera was consistently ~90
(none of these are scientific, just quick runs with other tabs open on a computer that's doing other stuff too)
A single run is not an effective way to compare these things. Anybody writing articles about JS benchmarks should know that by now.
